ABSTRACT:
The invention relates to the forming of a control pulse for the transmitter in a GSM radio telephone system. A cos.sup.2 pulse is formed by means of an analog circuit from a rectangular pulse which is first shaped into a triangular pulse which may be somewhat clipped at its peak. The triangular pulse is further shaped into a cos.sup.2 pulse. The circuit also includes the selection of the abruptness of the triangular pulse and, thereby, the abruptness of the cos.sup.2 pulse.
